SOLDERING-IRON.

Specification of Letters Patent.

Patented aan. 23,1912.

Application tiled J une 23, 1909. Serial No. 503,829.

Be it: knownthat I, JAMES E. Rowe., a citi- Zen` ot'he United4 States, and a. resident of the city of New York, borough of Manhattan, in the county and vState of New York, have invented' a new and useful Improved Soldering-Iron, of which the following is a full, clear, and exact description.

This invention relates to a new and improved self-heating soldering iron; which is adapted to be heated by a gas supplied from a suitable vaporizable fluid stored in the body of the device.

Arr object of the invention is to provide a. devine-Which will be simple 1n construetion, rsafe. and et'cient i-n its operation, and

at the same time-strong and du able A further obj-ect of the invention is to provide means whereby the fluid to be vaporized may befreely and positively fed witboutdanger of intermixing air.

Theseand further objects, together with i the construction and combination of parts.

, 3 is a fragmentary vertical section at rightangrles to the section taken in Fig. Q: and

Fig. 4 is a detailview, partly in section. ot' the vaporizing head.

Referring more partirularly to the Separate parts-gl indieates the body of the de` vire, which consists preferably of a hollow cylindrical easing. which is closed at one end by an end 2, secured to the cylindrical 'portion in any well-known manner. as by 'lneane` of a screw-thread, and whu'h has a .screw-threatded .central openin-, r therein which is adapted to be closed by `a suitable ,handle Il. whichserves the :u ldit'ional purpose. of' forming a stopper.l 'The .other end of theeasing 1 is closed `by a suitable end 4. whieh is secured in any well-known inan- 'nel'. .as by meanswff Screw-thi aded engagemon-t.v -The partphl., 2 and 4 form a romr Y Y 'lrlettrreservo.r on container, which-1S adapted to' store. a Suppitiy of suitable hydro-carbon luid. l A

Within theejafslng 1,V there 1s providedn suitable intake 5. which is preferably in the .form of a cylindrical pipe having ain opening at each end, which openings are in the form of valve-seats, and are adapted to be closed by suitable valves 6 and 7 on the end of a lconnecting rod S, which is slightly longer than the intake pipe 5. y

Leadingr into the intake 5 and secured thereto intermediate its ends in any wellknown manner', there are providedia plurality ot' supply pipes 9 and 10. which are adapted t'o receive through the'intake 5 a suitable luidfsueh as gaisolene. benzine or the like. with which the easingr 1 is`tilled.

The other ends ot' the pipes 9 and,- 10`are seby any suitable means. such' as screwthreaded engagements. and form aoontinuation ot' the openingel 11 and 12. These pipes -13 and 1l are secured preferably b v screwthreaded eugag'ementat their opposite ends, to a vaporizer 15. which is in the form of a hollow ring havingr a screw-threaded flange 16 thereon.' which is adapted to be engaged by a hollow .solderingr head 17. The soldering' head 1T ha:-.l the usual pyramidal end. and also has perforations in thesides thereot'. to permit the gases ot' eombustion to escape.

ln order to `draw otf the gases vaporized in the vaporizer '15. there is provided a suitable pipe lt), which isipreterably connected to the vapori/.er l5 by Screw-threaded engagement, and also connected at its other end to the. end 4- in any well-known manner. rlhere is provided au opening' 2.0 in'the end t in alinement with the opening in the pipe lf). (onneeted to this opening r 20, there is provided a suitable valve-.seat 2.1, coperating;r with whit-h there is prt-)vided a suitable needle-valve, 22. The needle-valve 2-2- is preferably screw-threauled, as at 23, in order that it. may .be toi-eed positively onto its seat, and is adapted to be operated in any suitable manner, as :by means of a thumbto the head 4 in any wel1known manner,

as by screwthreaded engagement, and acts a-s a burner for the progecting hydro-c-ar- 1 bon vapor.

Surrounding the nipple 26, and secured l a plurality of openings 28 therein, through which the air isj adapted lto be drawn, to mix with the burning gas.

The operation of the device will be read` ily understood from the above description.

Vthen it is desired to fill the casin'g or reservoir 1 with a suitable fluid, the handle l burner connected to said reservoir, a tube' 3 is removed and the liquid poured in. In

usingr the device, the opening which supplies the intake will. always be under the liquid, prf 'ded there is sufficient liquid in the reservoir, no matter 1n what position the soldering iron is held. lf the soldering iron is extended downwardly, in Fig. 2, theva-lve. 6 will automatically seat by gravity on'the opening at the upper end of the intake 5, at thesame time removing the valve 7 from thefopening at the bottom of the intake 5. If, however, the soldering iron is inverted, the reverse condition of affairs will take placeg-tliat is, the valve 7 will rest tightly on its seat, and the valve 6- Will bein al position away from its seat. The purposetof this is to permit only the hydrocarbon liquid to be fed to the supply pipes 9 and 10, and thus toitthe vaporizer 15.

By heating the vapor er 15, a. steady t stream of vaporized gas is forced out -through the nipple Q6, where it comes'in direct contact with the air drawn into the openings 28 in the combustion shell 27.

The amount oi as fed-to the nipple QG may be accurately regulated by the needle valve 22. The jet of burning gas is proi `jected directly into and in alinement with the soldering head 27, and the products of openings 18, thereby thoroughly heating the soldering head 17, and at'the same time heating the vaporizer 15.

It it is desired, the head 1.7 may be relmoved from the rest of the device, and a practical, self-contained torch is thereby l provided.

Having thus described my invention, I claim as neuand desire to secure by Letters Patentcombination with a fuel reservoir, of a within said reservoir, open at each end, means connected to said tube intermediate its end, for conducting the fuel to said burner, a rod slidingly mounted iu said tube, and. valves on the end of said rod adapted to normally maintain one of the open ends of said tube. closed at anyone time.

9,. [n aderire olf the class described, the combination with a. fuel reservoir, of a within said reservoir, 'open at eacl1-'ei1d, means connected to said tube intermediate its end, -i'or conduct-ing the fuel to said burner, a rod of greater -length than the length ot said? tube, slidingly mounted in said tube, and valves on the end of said rod adapted' toE normally maintain one of the open ends in, said tube closed at any one time.

In testimony whereof I have signed my name t6 this specification in the presence of two subscribing witnesses.'
